Actions from the Last Meeting
Minutes of the code management group meeting 2016-09-23
- (ongoing) GM to check 8.4 versus 7.3 (and possibly vn8.4 vs 10.x) GLOMAP-mode code and report any missing bug fixes on the bugfix page.
- (ongoing) FOC to incorporate Bug #35 and others into dry deposition work
- (ongoing) LA to migrate PUMA UM tickets to MOSRS
- (ongoing) UM #368 (RAFEPS value). Error not encountered at UM10.x but LA to consult Oliver Wild regarding background and implications.
- (ongoing) LA to check doc for NVOC factor and open ticket to remove it from code
- (ongoing) CJ to lodge STASHmaster changes to diagnostics that should make use of UKCA time availability codes
- (ongoing) CJ,FOC,AH,AS,LA and John H to decide best way forward for implementing GLOMAP-climatology code and documentation.
- (ongoing) JM,BJ,NB to discuss incorporation of Nicolas' RADAER description into UKCA (or separate UMDP). JM to take lead.
- (ongoing) FOC to open ticket + Bugfixes Table entry related to 'Unable to calculate tropopause' warnings
- (updated) MD to setup Strat+Trop suite as soon as GA7.1 is frozen and also add to Rose-stem. MD set-up/replace current Rose stem job with GA7.1 jobs.
- (ongoing) CJ to involve NS in discussions with Dynamics and UM-sys teams regarding movement of UKCA call, for effective implementation of water vapour feedback.
- (ongoing) FOC to recommend at next Exec meeting a policy of allowing only CMG to (certify and) distribute any UKCA configurations for science purpose.
- (new) MD to chase CMS about MASS archiving
- (new) NS to collate all code that could be removed and put on Wiki
- (new) LA to do doodle poll for end of Nov/ start of Dec
Standing actions
- (ongoing - standing item) CMG to monitor list of bugs and circulate between group for owners.
- (ongoing - standing item) At CMG future meetings there should be included an appendix listing the open bugs. If a ticket is included it is not an open bug (as the owner of ticket is person doing lodging).
- (ongoing - standing item) JM to continue to link/send powerpoint results (re: GA7.0/GA7.1), as new configurations released and link/put files on UKCA wiki.
- (ongoing - standing item) ALL with access to keep monitoring ukca_bugs email list.
- (ongoing - standing item) ALL to think about if code changes will change KGO and let systems team know in good time. This should be a standard part of our working practice.
- (ongoing - standing item) ALL to review and remove obsolete code
Bugs/Bugfixes
Open Bugs
# | Description | Ticket | Owner | Status/ Updates | Comments from previous meeting | Comments from this meeting |
---|---|---|---|---|---|---|
31 | FP exceptions in asad_sparse_vars or asad_spimjmp |
#368 (MOSRS) | Nick Savage | leave open. vn10.x seems to be better | ||
35 | Error in labelling: Surface resistance <--> stomatal resistance ? | MOSRS #1409 | Fiona O'Connor | open - folded into DD. FOC to update | ||
50 | ukca_solve_coagnucl failures | #319 (MOSRS) | Mohit Dalvi/Graham Mann? | Not encountered any more ? | dissapeared at vn10.x | |
57 | Incorrect logic for DMS anciliaries required | #756 (MOSRS) | Nick Savage | trivial. Might close as wontfix, but might want to do in RAQ | ||
68 | HO2 heterogeneous loss rate 1st order(?) | No ticket | Nick Savage | NS to look at that. Leave open to review | ||
72 | UKCA Dry Deposition: Surface resistance values not set for some species |
#1250 | Alan Hewitt? | discussed above, have way forward | ||
74 | Bug in ukca_tropopause with definition of PV tropopause | #1283 | Steven Hardiman | Change ownership? | discussed above, wrap together issues. Fix is separate from #75 | |
75 | Bug in STE fluxes | #1367 | Fiona O'Connor | could be endgame. Needs further work | ||
80 | H2O feedback broken under ENDGAME | UM#1646 | Colin Johnson | discussed above, keep open |
What is required now to move UKCA recommended jobs up to GA7.1? (CJ)
Highlights from vn10.8 (LA)
vn10.8 UKCA tickets
UMPB May 2017 Highlight Report
- CJ: Water vapour feedback - This includes flux calculations of water production and loss available in stash, as well as a diagnostic which gives the change to q calculated at each timestep. (#1646 & #3123)
- LA: Quasi-Newton steps in Newton-Raphson solver - speeds up the model by ~2-3%. Will not bit-compare with runs without it however. (#2819)
Targets for vn10.9
Virtual Machine
UM Virtual Machine Guide - Note: this will be superseded by UMPB X10 from vn10.8 onwards.
